What Is an Isolated Power Supply Module?

An isolated power supply module converts high-voltage AC into low-voltage DC while electrically isolating input and output. Isolation prevents dangerous high voltage from reaching the low-voltage circuit.

This provides:

Safety from electric shock
Protection for components
Noise reduction
Reliable performance

It is essential in smart electronics and automation systems.
